Heaven Fresh XJ-2100UV Ionic & UV Air Purifier
sounds so good.
i like the UV light feature
was hoping if you guys could read the spec and see if this is a good one or not, coz i don’t know anything about it
UV light does not kill bacteria, it just inactivates them. The best air purifier is your air conditioner with ozone electrodes.
never heard of it, use the Sharper Image product myself.
No. Here is why: That UV light that catches your attention isn’t going to work as they claim. That is because ultraviolet light works as a sanitizer because is interferes with the replication of DNA. That means organisms can’t function at the cellular level. A good thing right? Well it is if you can get enough contact time for the UV light to do its work. The problem is that whatever you are trying to sanitize is flying by that bulb so fast, there is not enough contact time for it to do its work.
The second thing is that ionizers produce trace amounts of ozone. Ozone is a lung irritant. It is the reason they tell asthmatics to stay inside sometimes, because there is a high level of ozone in the air. So, the purifier that you want to buy to clean the air will actually pollute it.
I am sending a link to an article that tells you all about the different kinds of air cleaners made, how to evaluate them for yourself, and how to calculate what you need based on the size of your room.
I personally have several Healthmates, because they work (I put a friend’s particle counter next to one of my machines to test it out once) and because you don’t have to spend lots of money buying filters, because they last so long. I’ll see if I can find a link to those for you also.
Don’t let the shiny UV light distract you from getting a machine that will really work…..and stay away from ozone producing ionizers!
